Dell XPS M1730: SLI, Penryn, and Overclocking

More 1920x1200 Gaming Performance

Considering the components in the M1730, it's no surprise that it places at the top of the performance latter on every single game we tested. In fact, we would have been shocked if it didn't do exactly that. (We'll ignore the Alienware m9750 winning in Quake 4... explanation coming in about two sentences.) If you're looking for a powerful gaming notebook, this is as fast as they come for the time being. We will take a closer look at SLI scaling performance on the 8800M in the near future, but outside of a few anomalies (i.e. Quake 4 with the beta driver currently has a bug where SLI actually hurts performance; we suspect with a few driver tweaks the 8800M GTX SLI can beat the Go 7950 GTX), there are clearly tangible benefits to running dual graphics cards. There are also drawbacks - more heat, power, noise, etc. - but as stated at the outset, this is not a notebook for everyone.
